拱主体钢结构施工技术研究

Research on construction technology of arch main steel structure

关于城市内部市政桥梁的建设,目前限制条件较多,同时施工技术研究也跟不上目前城市的快速发展,以典型的提篮拱桥梁钢结构为对象,对其加工制作,现场的安装以及拼接、临时支架的设计以及桥面和钢拱安装关键技术要点进行了分析研究。

The construction of the city within the municipal bridge has at present many restrictive conditions. At the same time,research on construction technology could not keep up with the rapid development of the city. Based on the typical structure of the steel girder arch bridge as the object,making the processing,installation and splicing,and the design of temporary support and installation of steel arch bridge make analysis and research.
